COSTO-EFECTIVIDAD DE PRUEBAS PARA EL DIAGNÓSTICO DE GEOHELMINTIASIS: REVISIÓN SISTEMÁTICA DE LA LITERATURA

Abstract

Introduction: The tests for diagnosis of the geohelmintiasis are diverse, with multiple studies that demonstrate heterogeneity in its diagnostic validity and few about its cost-effectiveness. Objective: To systematize the economic evaluations on the tests applied in the diagnosis of geohelminths. Methods: Systematic review in six databases with 24 search strategies. A protocol for the selection of the studies was applied, guaranteeing completeness, reproducibility and evaluation of methodological quality. Qualitative synthesis of the information was made. Results: In the scientific literature there are four complete economic evaluations (cost-effectiveness studies) for the diagnosis of geo-helminths; in these, five tests were evaluated in 247 adults and 6,708 children. In the health outcomes the studies employed the proportion of positive patients and some diagnostic validity parameters such as sensitivity and specificity, while costs were limited to inputs and salaries. These findings show the low application of the theoretical and methodological resources of health economics in the diagnosis of soil-transmitted helminth infections. Conclusion: The economic evaluations of tests for the diagnosis of geohelminths and intestinal parasites in general are meager worldwide and the few available studies have limitations of internal and external validity that prevent the application of their results to other areas.
